What else can I help you with?
A flat thoracic muscle deep to the pectoralis major that acts to draw the scapula inferiorly or to elevate the rib cage?
The muscle described is likely the serratus anterior. It originates on the surface of the upper ribs and inserts along the scapula. Its primary functions include protraction of the scapula (bringing it forward around the ribcage) and upward rotation of the scapula.
What is the strongest protractor of the scapula?
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
Moves the scapula forward and downward?
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
What are examples of flat bones?
Examples of flat bones in the human body include the skull bones, sternum (breastbone), scapulae (shoulder blades), and ribs. These bones provide extensive surface area for muscle attachment and protection for underlying organs.
Which muscle attaches onto the cartilage of ribs five through seven?
The serratus posterior superior muscle attaches onto the cartilage of ribs five through seven. This muscle is located in the upper back and is involved in assisting with respiration by elevating the ribs.
A flat thoracic muscle deep to the pectoralis major that acts to draw the scapula inferiorly or to elevate the rib cage?
The muscle described is likely the serratus anterior. It originates on the surface of the upper ribs and inserts along the scapula. Its primary functions include protraction of the scapula (bringing it forward around the ribcage) and upward rotation of the scapula.
Small inspiratory muscle between the ribs elevate the ribs?
External intercostal
Muscle that daises ribs in forceful inhalation?
Rhomboideus Major The rhomboid major helps to hold the scapula (and thus the upper limb) onto the ribcage. It also acts to retract the scapula, pulling it towards the vertebral column, and downwardly rotates the scapula with respect to the glenohumeral joint. It works collectively with the levator scapulae to elevate the medial border of the scapula.
What is the strongest protractor of the scapula?
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
Which muscle protracts and depresses the scapula?
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
What muscle raises ribs in forceful inhalation or pulls scapula forward and downward?
Rhomboid Major
Moves the scapula forward and downward?
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
Where is the orgin of the pectoralis minor?
The pectoralis minor muscle originates from the anterior surfaces of the third, fourth, and fifth ribs, near their costal cartilages. It then extends to insert onto the coracoid process of the scapula. This muscle plays a role in stabilizing the scapula and assisting with movements of the shoulder.
What bone does the spine attach?
the skull, pelvis, ribs, and scapula
What large muscle located the chest respiration?
There are several muscles involved in breathing:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)Diaphragm (Prime mover of inhalation)When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
What muscle is the flat bone attached to?
there are several flat bones... The Scapula (shoulder blade), Sternum (breast bone), Cranium (skull), Pelvis and Ribs are all considered to be flat bones.
Which bone joins the ribs to the top of the arm?
I believe you are looking for the clavicle. It connects the sternum to the scapula.
